Ff. Becker et al., THE REMOVAL OF HUMAN LEUKEMIA-CELLS FROM BLOOD USING INTERDIGITATED MICROELECTRODES, Journal of physics. D, Applied physics, 27(12), 1994, pp. 2659-2662
An electroaffinity column containing an interdigitated microelectrode
array was used to retain human leukaemia cells dielectrophoretically a
nd thereby separate them from normal blood cells. The leukaemic cells
could be subsequently released by removal of the dielectrophoretic fie
ld and collected. This novel approach exploits the differential dielec
tric properties of cells as a sorting criterion and has applications i
n medicine, biotechnology and environmental settings.
